But many decisions by other people will necessarily affect you. The color your neighbor paints their house will affect your property values. Decisions by random people to move to your town affect how much water you'll have, how much space will be available for you in public spaces, and on and on. If food store owners decided your area is no longer safe enough, they'll all leave and how far will you drive for food?

Your "independent" clothing choices will affect decisions made by buyers. Small influence from you alone, but the aggregate drives the clothing and fashion industries.

I think I see what you're getting at, and that used to work in the old days. Now, there are too many people, and the ramifications of that make actual independence difficult, if not impossible. I agree that independence is highly desirable, but our society took the overpopulation road over my objections.

Why use different logic for economics and politics? More people, more companies, more different products, more choices, yet somehow on the political spectrum the increase in population should lead to less choices and less independent fractions?
